Abstract

A bicycle carrier mounted at the rear end of a vehicle for transporting from one to four bicycles having demountable front wheels. The carrier includes a lower rack rearwardly of the vehicle and an upper rack supported by the lower rack above the rear trunk of the vehicle. Each rack includes an elongated horizontally mounted frame extended transversely of and within the transverse confines of the vehicle. Mounted on each frame associated with each bicycle to be carried thereon is an upwardly facing trough or channel member for receiving and supporting the rear wheel of a bicycle. In linear alignment with the channel member, a fork stanchion is mounted on the frame for supporting the front wheel fork of the bicycle. The front wheel is supported on a wheel stanchion which is mounted on the frame beside the front wheel fork stanchion. A retaining arm assembly on the frame yieldably urges the rear wheel into the channel member when the front wheel fork is locked on the fork stanchion. Bicycles transported on the carrier are positioned in a side-by-side relation and are located within the transverse confines of the vehicle.

Description

BACKGROUND OF THE INVENTION

The invention relates generally to a carrier for transporting bicycles by a vhielce and more particularly to a bicycle carrier mounted at the rear of the vehicle and supporting the bicycles in an upright position transversely of the vehicle.

Devices for carrying bicycles on vehicles are well known in the art. Most devices, including those described in U.S. Pat. Nos. 4,442,961 and No. 4,524,893 support the bicycles atop of the vehicle in an upright position and oriented longitudinally of the transport vehicles. The bicycles in this position extend substantially above the top of the vehicle and are directly in the slipstream of air created by the moving vehicle thereby adding greatly to the air resistance that must be overcome to move the vehicle at normal driving speeds. The upright bicycles, moreover, must be removed from the carrier if the vehicle is to be driven into a residential garage, commercial parking garage, or other area having a restricted height entrance. Loading and unloading bicycles from such carriers is difficult, requiring that the bicycles be lifted above the top of the vehicle while being balanced upright.

Other prior art devices mount a fully assembled bicycle transversely at the rear of the vehicle. This reduces the air resistance of a transverse bicycle, but results in the outer end portions of the bicycle extending outside the transverse confines of most commercial passenger cars. Care must be taken with carriers of this type to prevent damage to the bicycle or vehicle from objects passing close to the vehicle. These carriers suffer also in that their capacity is typcially limited to one or two bicycles.

SUMMARY OF THE INVENTION

The invention consists of a carrier for bicycles mounted at the rear of a transport vehicle. The carrier includes a horizontal frame extended transversely of the vehicle and detachably supported on the vehicle by a mounting bracket secured to the underside of the rear of the vehicle for convenient removal of the frame from the vehicle.

With the front wheel of the bicycle removed, the rear wheel thereof is positioned in a channel member at one end of the frame, and the front wheel fork is securely supported on a form stanchion at the opposite end of the frame and in linear alignment with the channel. A rear wheel engaging member on the frame yieldably urges the rear wheel downwardly into the channel and toward the fork stanchion. The removed front wheel is securely attached in an upright position on a wheel stanchion and associated wheel rest mounted on the frame to one side of the fork stanchion.

Two corresponding pairs of the channels, wheel and fork stanchions, and wheel engaging members can be combined on one frame to comprise a rack for two bicycles. A second rack may be mounted on the first rack to carry an additional pair of bicycles to provide for the transport of four bicycles with a single vehicle.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

Illustrated in FIG. 1, generally at 10, is a bicycle carrier of the present invention shown mounted at the rear end of a transport vehicle 12. A mounting bracket 16 for the carrier 10 supported on the underside of the vehicle 12 includes a pair of transversely spaced mounting tubes, one of which is illustrated at 14, that are located generally below the rear bumper 18.

The bicycle carrier 10 consists of a pair of

bicycle racks

20 and 22 to be hereinafter referred to as lower rack and upper rack, respectively, each of which is adapted to carry a pair of bicycles in upright side-by-side positions extended transversely of and within the transverse confines of the vehicle 12. Since two bicycles may be similarly carried on each of the pair of racks, only the lower rack 20 will be described in detail, with the corresponding elements of the upper rack 22 being indicated by like numerals.

The lower rack 20 (FIGS. 1 and 3) has an elongated frame 32 positionable transversely and horizontally of the vehicle that includes a front longitudinal frame member 34 and a rear longitudinal frame member 36 which are interconnected by

end member

38 and 40 and a central cross member 42. A pair of longitudinally spaced upright

tubular posts

25 and 27 are detachably secured to the frame member 34.

Transverse braces

44 and 46 corresponding to the

post members

25 and 27, respectively, extend from the lower end portions of the

support posts

25 and 27 to the rear frame member 36. The lower rack 20 is supported on the vehicle 12 by a pair of

support rods

28 and 30 secured to and projected horizontally forwardly of the lower end portion of the

support posts

25 and 27 for reception within the mounting tubes 14 of the bracket 16.

For receiving the rear wheel of a first bicycle there is welded between end member 38 and central member 42, at a position adjacent the front frame member 34, an upwardly facing trough or channel 48. In a similar manner, a second trough or channel 50 is secured between cross member 42 and end member 40, at a position adjacent rear frame member 36. As best illustrated in FIG. 7, for the channel member 50 each channel member includes a horizontal bottom web portion 52 and diverging

leg portions

54 and 56. The

channels

48 and 50 are of a size to accommodate and retain a rear bicycle wheel and tire, illustrated in FIG. 7 at 62.

Mounted on the end member 40 of the rack frame 32 and adjacent to the channel member 50 is a first rear wheel retaining arm 64 corresponding to the rear wheel of a first bicycle. The lower end portion of the retaining arm 64 is received between a pair of ears 66 on the end member 40 that extend inwardly of the rack frame 32. The retaining arm 64 is pivoted ona rod 68 extended between and supported in the ears 66 and the lower end portion of the retaining arm 64 (FIG. 7) for pivotal movement from a horizontal, folded position to a rigid upright or operative position. A second rear wheel retaining arm 70 for a second bicycle, corresponding in structure to the first retaining arm 64, is shown in FIG. 3 in a pivotally moved position.

Connected at the upper end of each of the retaining

arms

64 and 70 is a biasing hoop 72 of a generally horse collar shape in side elevation that is pivotally mounted on a pivot pin 74 (FIG. 8) for pivotal movement in a vertical plane above the corresponding trough or channel. The hoop 72 is formed from an elongated member of a U-shape in transverse cross section which is bent into the arcuate horse collar shape to provide a concave outer peripheral surface of a width to receive a portion of a bicycle tire or near wheel 62, as illustrated in FIG. 8. A coil spring 76 (Fig. 3) is arranged in tension between an ear 78 located on the retaining arm below the hoop 72 and a pivot arm 80 which is secured to and extends radially from the pivot pin 74. The coil spring 76 coacts with the configuration of the hoop 72 to continuously and yieldably urge the biasing hoop 72 downwardly against the rear tire and wheel 62 of a bicycle 82 carried on the rack, as illustrated in FIG. 4, to retain the rear wheel 62 in the channel 48.

Before mounting the bicycle, indicated at 82 in FIG. 4, on the rack 20, a front wheel and tire 86 of the bicycle is removed from its associated front fork 84. With the bicycle positioned on the lower rack 20 with the rear wheel 62 in the channel member 50, the front fork 84, as best seen in FIG. 5, is supported on a fork stanchion 88 that is bolted to the end member 38 to the rack frame 32 in linear alignment with the trough or channel 50. THe upper end portion of the fork stanchion 88 carries a hub 90 of a size to be received between the terminal portions of the front fork 84 which is formed with conventional slots (not shown). A commercially available quick relese lever 92 is inserted through the aligned slots and hub member 90 to secure and lock the front fork 84 to the fork stanchion 88. (FIG. 5).

It is seen, therefore, that with the front fork 84 locked on the stanchion 88 and the rear wheel 82 biased downwardly and toward the front fork stanchion 88, the bicycle is positively held against lateral and longitudinal movements relative to the rack frame 32.

For carrying the removed front wheel 86 of the bicycle 82, a front wheel stanchion 94 is bolted to the rear frame member 36 intermediate the end member 38 and the central cross bar 42. (FIGS. 3 and 6). The upper end portion of the wheel stanchion 94 is bifurcated to form a slot 96 for receiving one end of a conventional quick release lever 98 to lock the front wheel 86 on the wheel stanchion 94, as best shown in FIG. 6. A U-shaped wheel rest 100 for the front wheel has one leg welded to the lower end portion of the wheel stanchion 94 and is secured to the frame member 36 by bolts 102. A wheel stanchion 106 and wheel rest 108 corresponding to the trough member 48 are bolted to the forward frame member 34 intermediate the central brace 42 and the end member 40, and are similar in construction and position to the wheel stanchion 94 and wheel rest 100.

The lower rack 20 thus efficiently supports a pair of bicycles longitudinally of the frame in a side-by-side relation, with the removed front wheels supported in upright positions opposite the front fork of the bicycles within the vertical and transverse confines of the carrying vehicle. If it is desired to carry 3 or 4 bicycles, the upper rack 22 is attached to and supported by the lower rack 20 to carry an additional pair of bicycles above the trunk of the vehicle. The upper rack 22, illustrated in FIGS. 1 and 2, is supported on the

vertical support posts

25 and 27 of the lower rack 20 by means of a pair of associated posts, 24 and 26, respectively, having lower end portions slidably received within the

tubular support posts

25 and 27, respectively. The upper rack 22 is thus firmly supported forwardly of the lower rack 20 with the rack frame 32a positioned longitudinally of and above the trunk area of the transport vehicle 12. The elongated frame 32a of the upper rack 22 and its assembly with the bicycle supporting elements are similar in construction and use to the like parts of the lower rack 20. Similar numerals with a suffix "a", therefore, are used to describe like parts. In this respect, it is to be noted that horizontal cross bars 114 and 116 serve to brace the elongated frame 32a of the upper rack in lieu of the

braces

44 and 46 of the lower rack 20.

To use the carrier 10, the mounting bracket 16 is initially attached to the underside of and at the rear of the vehicle 12. Since the mounting tubes 14 are positioned below the vehicle rear bumper and generally underneath such bumper, the mounting bracket 16 may safely remain on the vehicle even upon removal of the carrier 10.

The lower rack 20 is attached to the vehicle by insertion of the

support rods

28 and 30 into the mounting tubes 14 and a retaining means, such as a cotter key 15 or lock pin (FIG. 1), is used to prevent accidental retraction of the support rods from the mounting tubes.

If one or two bicycles are to be transported, only the lower rack 20 need be used. In transporting 3 or 4 bicycles, the upper rack 22 would also be used. In this event, the bicycles to be carried on the uppe rack 22 would be initially mounted for convenience prior to the mounting of the bicycles in the lower rack.

It is understood that the foregoing description of the preferred embodiment may be modified or changed by one skilled in the art without departing from the spirit and scope of the invention as defined in the following claims:
